To perform the Master Reset, carefully unplug the washing machine from the power outlet and leave it unplugged for one minute. After one minute is up, plug the washer cord back into the wall. Next, open and close the door of the washing machine 6 times within 12 seconds to send a “reset” signal to all the components. (This is a common fix that many appliance repair mechanics use – it works on about 50% of all washing machines.) Once the reset has been completed set the washer to do a small load with no clothes in the washer. See if the washer goes through with the cycle as normal. If the washer performs correctly, then it has been reset and is fixed. If not refer to more troubleshooting techniques and causes of problems below.

If that did not solve the problem then it may be the “Lid Switch”. Top loading washing machines that have a faulty lid switch will not turn the agitator and the spin cycle will not start. However on some washing machine models it will still agitate but not spin. To properly check this you must remove the lid switch. (The lid switch is inside the washing machine main housing near the door frame.) The proper procedure for removing the switch will vary by different washing machine models so look in the users manual guide that came with your washer for the proper removal procedure. Or type in your washing machines model number and company manufacturer into Google and do a check for “Washing Machine Remove Lid Switch Model# Serial#”. Remember to unplug your washer before you begin any testing or repairs. Once the switch is removed keep the wires coming from the washer attached to it so you can test it with a digital multimeter. Press the button on the switch to simulate closing the lid. When you have the lid CLOSED (button pressed in), the switch should have continuity. When the lid is OPEN (button not pressed in), the switch should have no continuity. If the switch does not have continuity when pressed in, the lid switch needs to be replaced. Find your washing machine lid switch. If the lid switch is functioning properly, go to the next step.

The second most common item to go bad in your washer is the “Water Level Control / Pressure Switch”. This is usually always the defective part when your washing machine pumps the water out but will not spin and also when the water overflows on your washer. You can check this yourself by removing the 4 screws that hold the control panel in place. Once removed you will see the Water Level Control Valve. To identify it look for the part with the small plastic tube attached to it. Once identified, pull the plastic hose off the water level switch and blow air into it. If the tube is clogged with soapy residue, then you can try forcing vinegar down the tube and in the switch itself by using a turkey baster as this will dissolve the soapy residue. If the switch is visibly cracked or burned you will need to replace it. To replace this switch, the proper procedure for removing the switch will vary by different washing machine models so look in the users manual guide that came with your washer for the proper removal procedure.
